Vocaloid:

Vocaloid:

For the second problem does multiplying the function by 1/2 on the outside make it "shorter" or stretch it out?

Vocaloid:

Hint: if you multiply your height by 1/2 are you taller or shorter than you were before?

kaylak:

shorter

Vocaloid:

Good So it is a vertical compression

Vocaloid:

Third one is a little hard to explain For a reflection across x-axis you want to multiply the outside of the function by -1 So the negative sign must be on the outside of absolute value symbols, brackets, radicals, etc.
